Remediation Plan

The Giant Mine Remediaton Project addresses the long-term containment and management of the arsenic trioxide waste, the demolition and removal of all buildings on the surface, and the remediation of all surface areas including the tailings ponds. It also includes water management and treatment options.

The Remediation Plan was developed after years of site investigations, research and extensive consultation with the public and with the Independent Peer Review Panel. From a possible 56 different management alternatives for dealing with the arsenic trioxide waste, the list was narrowed down to the 12 most viable options.

Following this extensive community consultation period, the 12 options were further refined to two options: one which would keep the arsenic trioxide waste in the ground ("leave-in") and another which would involve removing it and storing it above ground ("take-it out"). These two options were presented to the public by the Giant Mine Remediation Project Office at several community meetings and public information workshops.
